Description

Technical Field

[0001] The utility model relates to the technical field of automobile rims, in particular to a detachable rim. Background Art

[0002] The rim, commonly known as the wheel rim, is a component on the wheel that mounts and supports the tire, and together with the spokes, forms a wheel. The rim and spokes can be integral, permanently connected, or detachable. There are two common types of rims: deep groove rims and flat bottom rims. In addition, there are split rims, semi-deep groove rims, deep groove wide rims, flat bottom wide rims, and full bevel bottom rims.

[0003] When most of the existing split rims are installed and spliced, the two half rims are generally fixedly connected only by bolts and nuts. During use, it is easy for the bolts and nuts to rotate due to vibration, resulting in loosening or even falling off between the two half rims. The connection stability is poor and needs to be further strengthened and improved. Therefore, in order to solve the above problem, the present application proposes a detachable rim. Utility Model Content

[0012] 1. The utility model has a reasonable structure. Through the coordinated setting of the mounting screw, the mounting nut and the mounting hole, the first connecting ring and the second connecting ring can be fixed together, and then the first half rim and the second half rim can be disassembled and replaced. When the fixing is completed, the limiting ring is taken and sleeved on the mounting nut, and the limiting teeth are aligned with the fixed gear ring. Through the coordinated setting of the fixed ball head, the ball head socket and the reset spring, the limiting ring can be fixed on the mounting nut. At this time, under the coordinated setting of the limiting teeth and the fixed gear ring, the limiting ring and the mounting nut cannot rotate, thereby effectively reducing the situation that the two half rims are loosened or even fall off due to the rotation of the mounting nut caused by vibration. After installation, it is stable and reliable, simple to operate, easy to use and practical.

[0013] 2. In the utility model, by using the first clamping strip and the second clamping strip to replace the setting of the fixed ball head, the ball head socket and the reset spring, the purpose of fixing the limit ring on the mounting nut can also be achieved, and another fixing method is provided for the installation of the limit ring, which is convenient for adaptation and selection according to actual conditions, and has better practicality;

[0014] 3. In the present invention, by setting the reinforcing rod, the torque force between the first connecting ring and the second connecting ring can be shared during the use of the rim for driving, so that the connection between the first half rim and the second half rim is more stable and reliable.

[0023] Embodiment 1

[0024] refer to Figure 1-Figure 4The detachable wheel rim shown in the figure comprises a first half rim 1 and a second half rim 2, a first connecting ring 3 is fixedly arranged in the first half rim 1, a second connecting ring 4 is fixedly arranged in the second half rim 2, a plurality of mounting screws 5 are evenly fixedly arranged on the side of the second connecting ring 4, a plurality of mounting holes matching the mounting screws 5 are evenly opened on the side of the first connecting ring 3, mounting nuts 6 are threadedly sleeved on the plurality of mounting screws 5, a plurality of locking components for locking the mounting nuts 6 are arranged on the first connecting ring 3, the locking components comprise a fixed toothed ring 7 fixedly arranged on the side of the first connecting ring 3, a limiting ring 8 is slidably sleeved on the mounting nut 6, a plurality of locking components matching the mounting nuts 6 are evenly fixedly arranged on the outer peripheral side of the limiting ring 8 The fixing gear ring 7 is matched with the limiting teeth 9, and a fixing unit is installed on the limiting ring 8. The fixing unit is used to fix the limiting ring 8 on the mounting nut 6. The fixing unit includes a plurality of fixed ball heads 10. The inner circumference of the limiting ring 8 is evenly provided with a plurality of sliding grooves. The plurality of fixed ball heads 10 are respectively slidably installed in the plurality of sliding grooves. The outer circumference of the mounting nut 6 is evenly provided with a plurality of ball head sockets. One ends of the plurality of fixed ball heads 10 extend into the plurality of ball head sockets respectively. The other ends of the plurality of fixed ball heads 10 are all installed with elastic reset elements. The elastic reset elements include a reset spring 11. The two ends of the reset spring 11 are respectively fixedly installed on the other end of the fixed ball head 10 and the side inner wall of the sliding groove.

[0025] By means of the above structure, the first connecting ring 3 and the second connecting ring 4 can be fixed together by the matching arrangement of the mounting screw 5, the mounting nut 6 and the mounting hole. When the fixing is completed, the limiting ring 8 can be taken and sleeved on the mounting nut 6, and the limiting teeth 9 are aligned with the fixed gear ring 7, and then the limiting ring 8 is pushed. During this process, the side of the mounting nut 6 will squeeze the fixed ball head 10 to shrink and avoid. When the fixed ball head 10 is pushed to the position corresponding to the ball head socket, the fixed ball head will be squeezed and pushed under the elastic force of the reset spring 11. 10 is automatically reset and inserted into the ball head socket to fix the limit ring 8 on the mounting nut 6. At this time, with the cooperation of the limit teeth 9 and the fixed gear ring 7, the limit ring 8 cannot rotate, and the mounting nut 6 cannot rotate either, thereby effectively reducing the situation where the mounting nut 6 rotates due to vibration and causes loosening or even falling off between the two half rims. After installation, it is stable and reliable. When the mounting nut 6 needs to be disassembled, the limit ring 8 can be directly pulled out with force. The operation is simple, easy to use and practical.

[0026] In this embodiment, a convenient pull tab 12 is fixedly sleeved on the outer peripheral side of the limiting ring 8. The advantage of such an arrangement is that, through the arrangement of the convenient pull tab 12, the staff can more conveniently take the limiting ring 8 for installation and limiting.

[0027] In this embodiment, a plurality of reinforcing rods 13 are evenly fixedly installed on the side of the first connecting ring 3, and a plurality of avoidance through holes adapted to the reinforcing rods 13 are evenly opened on the side of the second connecting ring 4. The advantage of such an arrangement is that, through the arrangement of the reinforcing rods 13, the torque force between the first connecting ring 3 and the second connecting ring 4 can be shared during driving, so that the connection between the first half rim 1 and the second half rim 2 is more stable and reliable.

[0028] Embodiment 2

[0029] refer to Figure 5 As shown, the fixing unit includes a first clamping strip 14 fixedly sleeved on the inner circumference of the limiting ring 8, and a second clamping strip 15 fixedly sleeved on the outer circumference of the mounting nut 6, and the first clamping strip 14 and the second clamping strip 15 are set with interference fit. The advantage of such a setting is that, through the interference fit setting of the first clamping strip 14 and the second clamping strip 15, when the staff pushes the limiting ring 8 with force so that the first clamping strip 14 passes over the second clamping strip 15, the limiting ring 8 can be fixed on the mounting nut 6. When the limiting ring 8 needs to be removed, the limiting ring 8 can be pulled outward with force, which provides another fixing method for the installation of the limiting ring 8, which is convenient for adaptation and selection according to actual conditions, and has better practicality.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
